Failure of the exhaust gas aftertreatment system in construction and aerial equipment is one of the most common causes of costly downtime on the job site. A clogged Diesel Particulate Filter (DPF), a faulty Exhaust Gas Recirculation (EGR) valve, or continuous SCR (AdBlue) system errors often force the machine into Limp Mode (power reduction).
For owners of aerial work platforms and telehandlers from JLG and SkyTrak, our company offers a comprehensive service to deactivate and program out these systems.
Which types of JLG machines do we work with?
The JLG brand is a global leader in the production of access equipment and material handling machinery. We service their entire fleet (including SkyTrak models), regardless of whether the machine operates under Tier 4 Final or Stage V emission standards.
Our services cover machines such as:
- Boom Lift Telescopic / Articulating
- Boom Lift Compact Crawler
- Scissor Lifts
- Telehandlers
- Rotating Telehandlers
Supported Models, Engines, and ECU Types (Technical List)
Effective AdBlue and DPF deletion requires precise software modification in the Engine Control Unit (ECU). We have extensive experience working with every drive unit used in JLG machines. Below is a list of the most popular configurations we modify on a daily basis:
1. JLG machines with Deutz engines (2.9L and 3.6L)
Deutz engines are the core power source for many boom lifts (e.g., models 400S, 460SJ, 600AJ, 1200SJP) and telehandlers (e.g., SkyTrak 6034, 6042). We work on advanced controllers, modifying their software non-invasively.
- Engine designations: D2.9L4, TD2.9L4, TCD2.9L4, TCD3.6L4 (Tier 4 Final)
- ECU Types: Bosch MD1CC878C and EDC17CV52
2. JLG and SkyTrak Telehandlers with Cummins engines (3.8L and 4.5L)
Models such as JLG 742, 943, 1075, or SkyTrak 10042 and 12054 are most often equipped with Cummins units, known for problematic NOx sensors and urea dosing modules.
- Engine designations: F3.8, QSB 4.5
- ECU Types: CM2350A, CM2350, CM2250A, CM2250
3. Compact boom lifts and scissor lifts with Kubota engines
In smaller machines, such as compact crawler lifts (X430AJ, X770AJ) or scissor lifts (RT series), Kubota engines dominate. We deactivate EGR/DPF systems in these units, restoring their full reliability.
- Engine designations: Z602, D902, D1105, D1305-E4B, V1505-E4B (Tier 4 / Stage V)
- ECU Types: incl. DENSO 275700-1022
4. Rotating Telehandlers (FPT and Perkins Engines)
The largest JLG rotating telehandlers from the R series require an individual approach due to the complex electronic architecture of FPT Industrial and Perkins.
- JLG R1385 / R13100 (FPT F4HGE413K Engine, 4.5L): ECU EDC17CV41 / MD1CE101
- JLG R1370 (Perkins 904J-E36TA Engine, 3.6L Stage V): ECU Denso A6E10 and A6E11
Why is it worth deleting emission systems in Heavy Duty equipment?
We perfectly understand that in the case of construction and agricultural machinery, time is money. The decision to deactivate the EGR, SCR, and DPF systems brings tangible benefits:
- Elimination of downtime: The machine will never enter "Limp Mode" (RPM reduction) again due to a lack of AdBlue fluid or a NOx sensor error.
- Cost savings: No need to replace astronomically expensive urea pumps, AdBlue injectors, or perform DPF regeneration/replacement.
- Greater engine reliability: Disabling the EGR valve ensures that only clean air enters the combustion chamber, which significantly reduces carbon buildup.
You receive full support from us, professional execution, and the certainty that the operation was carried out correctly and comprehensively.
